Privacy policy
How Tiệm Trà Nhỏ handles saves, accounts, analytics and advertising.
Updated: 26/09/2026Recommendations and campaign measurement
We recommend our products and partner sites. Browser storage limits repeated recommendations and remembers pauses after closing or clicking. Cloudflare Analytics Engine records campaign, placement, language, device category and event type; selected impressions and clicks also go to our existing analytics services. Effective impressions require at least half the placement to be visible for one continuous second. Links carry referral and UTM parameters. Destination websites handle subsequent activity under their own policies; clicks are not registrations or purchases.
Display banners
We also load third-party banners from highrevenueformat.com. The provider receives connection information such as your IP address and browser details and may use advertising identifiers. Closing a banner hides our banner slots for the current tab’s browsing session using sessionStorage; it does not reverse data already sent to the provider.
Local and online play
Local play does not require an account. Its progress, settings, daily snapshots and invitation reminders are stored in your browser. Clearing site data can erase them. A local save is not automatically uploaded to an online shop.
Google sign-in
If you choose online play, Google authenticates you. We store your Google account identifier and first name to recognize your account. We do not receive your Google password or request access to Gmail, Drive or contacts. A necessary, secure session cookie keeps you signed in for up to 30 days; signing out revokes that session.
Online shop data
We store your online shop progress, game actions, shop name, preferences, invitations, friend relationships and weekly scores on Cloudflare. We keep recent operation receipts to prevent duplicate transactions and recent daily snapshots to help recover errors. Online progress is separate from your local shop.
Visits and rankings
Online shops start private and rankings start disabled. You can allow friends or any signed-in player to visit. Visitors see your shop name, menu, tagline, upgrades, day and rating. They do not receive your cash, inventory, full save or Google identifier. Opting into rankings displays your shop name and score; you can turn this off in Shops & friends → Privacy. Worldwide ranking display changes can take up to three minutes. Visit permissions are checked when you visit. Invitation links show the inviting shop name and expire after seven days.
Analytics and service providers
The website uses Google Analytics 4 and Pageview (app.pageview.app) for page visits and selected game events, such as starting a day or switching game modes. These services process browser and request information according to their policies; Google Analytics may use cookies. Our custom game events do not contain shop names, Google identifiers, emails or save files. Cloudflare hosts the site and database and processes requests for delivery and security. Hashed network identifiers may be used temporarily to limit abusive sign-in requests.
Advertising and Google cookies
We have integrated Google AdSense code. Where ads are served, Google and third-party vendors may place or read cookies, use web beacons and process IP addresses, device/browser information and other identifiers to deliver and measure ads, limit repeated ads and prevent fraud. Google advertising cookies allow Google and its partners to show ads based on prior visits to this site and/or other websites. The presence of the code does not mean ads are available on every page.
Advertising choices
You can manage or opt out of personalized Google advertising in Google My Ad Center. You can also visit YourAdChoices for participating third-party vendors. These choices do not necessarily remove all ads and may depend on your browser, device or signed-in account. Read how Google uses information from partner sites and Google advertising technologies. Browser settings let you block or delete cookies; this can sign you out or affect features. Where consent is required, advertising must follow the applicable consent choices; this policy itself is not a request for consent.
Retention and requests
We retain online account and shop data to provide your saved game while the account remains in use. Contact us to request access, correction or deletion. We verify requests and explain any information that must be retained for security or legal reasons. Technical logs, recovery copies and service-provider records can have different retention periods; we do not promise immediate removal from all backups.
Children and personal information
The game does not need a real name in a shop name or slogan. Do not publish personal contact details there. If a parent or guardian believes a child provided personal information that should be removed, contact us. Use of any child-directed advertising must follow the applicable restrictions; we do not ask players for sensitive information to personalize ads.
Your choices and contact
You can play locally without Google sign-in, sign out, change visit permissions and hide your ranking. Clearing browser data removes local progress but does not delete your online account. For questions or a request to remove online account data, contact [email protected]. We will need to verify that the account belongs to you.
